PROBLEM TO BE SOLVED: To obtain high performance of nickel-acid lithium positive electrode plate which is improved in contact condition of a collector and an active material, by holding nickel hydroxide to a conductive porous body, and then, impregnating lithium nitrate solution, and after that, applying a heat treatment. SOLUTION: To a porous body having a conductivity as a collector, such as a porous body of nickel, carbon, aluminum, or stainless steel nickel hydroxide is held, and then, lithium nitrate solution is impregnated, or lithium nitrate is filled, and after that, a heat treatment is applied to manufacture a nickel-acid lithium positive electrode plate. Since an active material is filled in the condition the current collecting structure is formed solidly, the contacting condition of the collector and the active material, or between the active materials each other, is improved, and the active material is charged and discharged evenly. Furthermore, by impregnating the lithium nitrate after oxidizing the nickel hydroxide into an oxy-nickel hydroxide beforehand, or by including cobalt to the nickel hydroxide, the performance of the positive electrode plate is improved. |
